The Nexus Between Plant and Plant Microbiome: Revelation of the Networking Strategies

Abstract

The diversity of plant-associated microbes is enormous and complex. These microbiomes are structured and form complex interconnected microbial networks that are important in plant health and ecosystem functioning. Understanding the composition of the microbiome and their core function is important in unraveling their networking strategies and their potential influence on plant performance. The network is altered by the host plant species, which in turn influence the microbial interaction dynamics and coevolution. We discuss the plant microbiome and the complex interplay among microbes and between their host plants. We provide an overview of how plant performance is influenced by the microbiome diversity and function.

Plant–Microbiome Crosstalk: Dawning from Composition and Assembly of Microbial Community to Improvement of Disease Resilience in Plants

“…Plant-associated microbial communities hinder the pathogen-oriented activities via competing for resources, locking key nutrients (i.e., iron) and producing pathogen-killing metabolites (such as antibiotics and toxins) that ultimately eradicate the pathogens [114,115]. Furthermore, plant-beneficial microbiota also interrupt the communications between pathogens and their corresponding hosts indirectly, by inducing systemic resistance in plants (described in later sections) [116]. Recently, the indigenous plant-associated microbial communities have attracted the attentions of the scientific community, owing to their functional benefits on plant health under challenging climatic conditions [117,118].…”

Elucidating the Rhizosphere Associated Bacteria for Environmental Sustainability

“…They are also versatile in composition and influenced by the plant host and environmental factors [21]. The root exudates attract beneficial bacterial species to the rhizosphere of plants, while some unwanted bacterial species are also lured [7]. The constituents of root exudates vary between plant species and cultivars, which leads to variation in the rhizosphere bacterial community.…”

“…The PGPB are agricultural bioresources that stimulate plant growth and productivity. They also incite plants' resistance to different phytopathogens in a wide variety of crops including vegetables, fruits, and some trees [7].…”

Studying Microbial Communities through Co-Occurrence Network Analyses during Processes of Waste Treatment and in Organically Amended Soils: A Review

“…Networks-that is, a collection of nodes (community members) establishing interactions (represented as links) among them as a system-are useful to find details on community assembly rules reflecting ecological processes (mutualism, competition, predation, etc. ), habitat filtering as well as mathematical coupling among different populations that regulate system functions in space or time [53,54]. If environmental and physicochemical conditions are included in the network analyses, the results reveal which conditions the microbial co-occurring assemblages of organisms prefer or avoid [55].…”
